Chelsea striker Diego Costa has discovered a groin problem while on international duty with Spain.

The 28-year-old played 90 minutes during Chelsea’s 5-0 thrashing of Everton on Saturday and got himself on the scoresheet against the Toffees.

The former Atletico Madrid forward flirted with a return to the Vicente Calderon this summer but Antonio Conte convinced him to stay and he’s repaid the Italian’s faith with nine goals in 13 appearances so far this term.

However, according to Spanish outlet El Confidencial, Costa arrived at Spain’s training camp with a groin injury and is now a doubt for his country’s upcoming games against Lithuania and England.

Spain boss, Julen Lopetegui, considered sending Costa back to London for treatment but decided that the forward could remain at Spain’s base to recover.
